Description
CROSS-REFERENCES TO RELATED APPLICATION
The present application claims priority from and the benefit of
Korean Patent Application No. 10-2017-0172610, filed on Dec. 14,
2017, which is hereby incorporated by reference for all purposes as
if set forth herein.
BACKGROUND
Field
Exemplary embodiments relate to an airbag apparatus for a panorama
roof, and more particularly, to an airbag device for a panorama
roof, which can prevent a passenger from being injured or thrown to
the outside even when the roof of a vehicle is damaged in case of a
rollover accident of the vehicle.
Discussion of the Background
In general, a vehicle transports passengers. The vehicle has airbag
devices to protect passengers. For example, the airbag devices are
installed at the front, both sides and the top of the vehicle. Each
of the airbag devices includes an inflator and an airbag. When a
certain magnitude of external shock is applied to the vehicle, the
airbag is expanded while gas generated from the inflator is
injected into the airbag. The airbag is rapidly expanded to protect
the body of a passenger. When the vehicle is turned over, the
airbag installed at the top of the vehicle is expanded. The airbag
is deployed toward the center from both sides of a panorama
roof.
In the related art, since the airbag at the top of the vehicle is
deployed toward the center from both sides of the panorama roof,
the center of the panorama roof may not be completely covered by
the airbag, which increases the possibility that a passenger will
be injured. Furthermore, since the support force of the airbag is
weak in the center of the panorama roof, the airbag may be
separated from the center of the panorama roof. Therefore, there is
a demand for a device capable of solving the problems.
The above information disclosed in this Background section is only
for enhancement of understanding of the background of the invention
and, therefore, it may contain information that does not constitute
prior art.

FIG. 1 schematically illustrates an airbag device for a panorama
roof in accordance with an exemplary embodiment of the present
invention, and FIG. 2 schematically illustrates that the airbag
device for a panorama roof in accordance with the exemplary
embodiment of the present invention is operated. Referring to FIGS.
1 and 2, the airbag device 1 for a panorama roof in accordance with
the exemplary embodiment of the present invention may include a
panorama roof 10, a roller 20, a head liner 30, an inflator 40, a
guide tunnel 50 and a cushion 60.
The panorama roof 10 may be disposed at the ceiling of a vehicle.
The panorama roof 10 may include two lines of windows. When the
window at the first line is slid, the panorama roof may provide a
sense of openness. Hereafter, the window at the first line will be
referred to as a first window, and the window at the second line
will be referred to as a second window.
The roller 20 may be disposed under the panorama roof 10, and a
blind 21 for covering the panorama roof 10 may be wound around the
roller 20. For example, when the blind 21 wound around the roller
20 is unwound to move to the front end of the panorama roof 10, the
blind 21 may cover the first and second windows of the panorama
roof 10.
The head liner 30 may cover the roller 20. For example, the head
liner 30 may indicate an interior material of the vehicle, and
limit the exposure of the roller 20 to the outside. The blind 21
may be moved over an end of the head liner 30.
The inflator 40 may be disposed at sides of the panorama roof 10,
the guide tunnel 50 may be connected to the inflator 40 to guide
gas, and the cushion 60 may be connected to the guide tunnel 50.
The cushion 60 may be covered by the head liner 30, and deployed by
the gas guided through the guide tunnel 50 so as to cover the
panorama roof 10. For example, the guide tunnel 50 and the cushion
60 may be integrated with each other.
Therefore, the gas discharged from the inflator 40 may pass through
the guide tunnel 50 and deploy the cushion 60. At this time, the
cushion 60 may be disposed adjacent to the end of the head liner
30, and thus rapidly cover the panorama roof 10.
FIG. 3 schematically illustrates the inflator of the airbag device
for a panorama roof in accordance with the exemplary embodiment of
the present invention. Referring to FIG. 3, the inflator 40 in
accordance with the exemplary embodiment of the present invention
may include a gas generation part 41 and a gas fixing part 42.
The gas generation part 41 may be exploded to discharge gas, when a
vehicle collision signal is received. The guide tunnel 50 may be
connected to a discharge port of the gas generation part 41, and
expanded by the discharged gas. For example, the gas generation
part 41 may be disposed at both edges of the frame of the panorama
roof 10.
The gas fixing part 42 may fix the gas generation parts 41 to both
sides of the panorama roof 10, respectively. For example, the gas
fixing part 42 may be coupled to the outside of the gas generation
part 41, and screwed to the rears of both edges of the frame of the
panorama roof 10. The gas fixing part 42 may be covered by the head
liner 30.
The gas generation parts 41 may be disposed at both edges of the
panorama roof 10, respectively, and the cushion 60 may be disposed
in the center of the panorama roof 10 and have a length
corresponding to the width of the first and second windows. The
guide tunnel 50 may connect the gas generation part 41 and the
cushion 60 so as to guide gas. Since the guide tunnel 50 includes a
harder material than the cushion 60, the guide tunnel 50 may be
suppressed from being deformed and induce the gas to move to the
cushion 60, while the gas is supplied. In addition, the guide
tunnel 50 may include the same material as the cushion 60.
FIG. 4 schematically illustrates the cushion of the airbag device
for a panorama roof in accordance with the exemplary embodiment of
the present invention. Referring to FIG. 4, the cushion 60 in
accordance with the exemplary embodiment of the present invention
may include a cushion deployment part 61 and a cushion support part
62.
The cushion deployment part 61 may be folded and connected to the
guide tunnel 50 before deployed. The cushion deployment part 61 may
be disposed above the end of the head liner 30. For example, the
cushion deployment part 61 may be disposed above the end of the
head liner 30, and the blind 21 may be disposed between the head
liner 30 and the cushion deployment part 61.
The cushion support part 62 may support the cushion deployment part
61. The cushion support part 62 in accordance with the exemplary
embodiment of the present invention may include a support guide
part 621 and a support coupling part 622.
The support guide part 621 may be disposed above the blind 21, and
support the cushion deployment part 61. For example, the support
guide part 621 may support the bottom surface and both side
surfaces of the cushion deployment part 61, and thus limit the
side-to-side movement of the cushion deployment part 61. In
addition, the support guide part 621 may support the bottom surface
of the cushion deployment part 61, and thus limit the backward
deployment of the cushion deployment part 61. At this time, the
guide tunnel 50 may be connected to the cushion deployment part 61
through the support guide part 621.
The support coupling part 622 may be connected to the support guide
part 621, and mounted on the panorama roof 10. For example, the
support coupling part 622 may be coupled to both sides of the
support guide part 621, and fixed to the frame of the panorama roof
10.
The operation of the airbag device for a panorama roof in
accordance with the exemplary embodiment of the present invention
will be described as follows.
The inflator 40 may be mounted at both sides of the panorama roof
10, and the roller 20 may be disposed at the front bottom of the
inflator 40.
The guide tunnel 50 may be connected to the inflator 40, and the
cushion 60 including the folded cushion deployment part 61 and the
cushion support part 62 for supporting the cushion deployment part
61 may be disposed at the end of the guide tunnel 50. The cushion
60 may be covered by the head liner 30 so as not to be exposed to
the outside, and the blind 21 which is wound around the roller 20
and unwound from the roller 20 may be disposed under the guide
tunnel 50 and the cushion 60.
When a vehicle accident occurs in the above-described state, the
inflator 40 receiving a sensing signal may be exploded to generate
gas. The generated gas may be moved through the guide tunnel 50 and
supplied to the cushion 60. The cushion 60 may be deployed by the
supplied gas and sequentially cover the second window and the first
window of the panorama roof 10, thereby protecting a passenger.
At this time, since the blind 21 is disposed under the cushion 60,
the cushion 60 may be suppressed from being deployed downward, and
rapidly deployed to the first window of the panorama roof 10.
In the airbag device 1 for a panorama roof in accordance with the
exemplary embodiment of the present invention, the inflator 40 may
be disposed at sides of the panorama roof 10 and covered by the
head liner 30, which makes it possible to guarantee a passenger's
safety when the inflator 40 is exploded.
Furthermore, since the blind 21 is disposed under the guide tunnel
50 and the cushion 60, the cushion 60 can be rapidly deployed
forward while suppressed from being deployed downward.
Although preferred embodiments of the invention have been disclosed
for illustrative purposes, those skilled in the art will appreciate
that various modifications, additions and substitutions are
possible, without departing from the scope and spirit of the
invention as defined in the accompanying claims.
